The OB is situated on private farmland which was accessed by kind permission of the farmer. It was built into a field boundary hedge beside a farm track through fields east of South Ferriby, to the east of a working gravel pit.

CART visited the OB site with John Andrew (son of patrol leader Sgt JM “Jack” Andrew) and Dennis Holloway in order to assess condition, take measurements and photographic records.

The OB was built into a field boundary - a slightly elevated grassed-over strip with a mature hedgerow growing on it, dividing a cultivated field from a farm track. (Above)

This is one of 15 Lincolnshire OBs that were built by John Sheffield of Scunthorpe with Royal Engineers’ labouring. It was constructed from prefabricated concrete panels that were bolted together. Breezeblocks were used for building both end walls.

The structure is in excellent condition, dry, and well ventilated, with vents in the central roof section as well as in the end walls. The size is 3.20L x 2.50W x 2.10m H and it is orientated N/S.

The OB is accessed with a ladder down a narrow drop-down shaft built from breezeblocks. The vertical shaft is 3m deep, the opening measures 0.90 x 0.80m.

The opening was originally covered by a steel lid with a tray containing soil and vegetation for camouflage on top of it

The cover was locked in its position by a key of the type that is commonly used for manholes. Turning the key would have lowered the cover which could then be pushed aside and into an adjoining steel case that is still in situ.

The OB has no emergency exit.

The interior walls were later painted blue and white, presumably by visiting teenagers.

Nothing of the original furniture remains. John Andrew remembers that the OB contained bunks made from wire netting nailed on a wooden frame.






The patrol used Rodine (a rat poison), which they mixed with water and sprinkled around the vicinity of their OB, in order to throw enemy sniffer dogs off scent. (IWM interview Dec 1994:


Other physical remains:  Steel case holding drop and slide cover; ceramic vent pipes; John Andrew has the original key used for opening steel lid (below)

Observation Post/s:  Currently unknown

Targets were Elsham Airfield and the Humber barges.

Locally within the area the patrol operated or at the regional headquarters at Wellingore, Blankney or Dalby. All patrols also went to Coleshill for specialist training. Patrol member Tom Andrew mentions (in: Mark Sansom, The Secret Army) how his father, Sgt JM Andrew, excelled in silent night movement and once also won a prize (at Coleshill) for planting explosives.

Tommy gun, later replaced by Sten guns; revolvers; a Beretta .32 pistol; .22 rifle with telescopic sights; plastic explosives; various detonators; detachable muzzle-mounted grenade launcher; commando knives and magnets for sticky bombs.

Many thanks to John Andrew and Dennis Holloway for taking us there.
